I was taking Saint Johns Wort before I started having heart palpitations. I went to the doctors and they gave me Propranolol for these palpitations. After a few days of taking them, the palpitations had reduced to heart flutters. It seems to me, however, that the adverse side effects are not worth it long term and it doesnt seem to reduce anxiety for me. The question i am asking is that if i should be taking them only when i need them, or should i try a different medication? I have tried taking Kalms as well, but this was before i taken St Johns Wort and they sort of worked. Should i go back to using Kalms?
